This paper reports on the effects of the late 2009 El Nino on the reefs at Palmyra Atoll National Wildlife Refuge, Northern Line Islands, Central Pacific.

A mild bleaching event occured (9.2% prevalence) in response to the elevated and sustained temperatures and we relate local environmental conditions to spatial patterns of bleaching.
